Pain is a natural warning system. Pain indicates that your body is getting damaged or your health/life is in danger. Pain is a signal that you’re crossing a boundary. A good thing.
Pain stimuli teach you where your limits are. Pain however appears to be experienced differently by each person. There are people who experience no pain at all or people who suffer from excessive and chronic pain. And everything in between.
Scientific research on pain shows one breakthrough after another. On the one hand, scientists have discovered the gene that creates the pain pathways in our tissue (or not for that matter). On the other hand, research shows how early life experiences may enhance subsequent pain perception. Think of premature babies who may have to undergo many painful treatments. This overactivates the formation of pain pathways in their tissue and makes them much more sensitive than other babies.
Not only is science now looking for drugs that can adjust the defective gene, without side effects. They also discovered how to give less space in your brain to pain by managing your attention, by positive emotions and decisiveness.
Early hospital trauma is frequently a key element in the stories of people who want to heal their inner child: the abandonment by the parents (especially the mother) and invasive medical procedures on the baby. Resulting in huge unsafety and panic that the baby has to undergo and massively stimulating the formation of pain pathways. In inner child work it is important to acknowledge that old pain and let it calm down. And sometimes it is necessary to learn as an adult today to set a boundary to this long ingrained pain. By mastering your emotions, by learning to direct your attention and learn to decide that a boundary is in order.
